Obada Alkasbeh won a cracking fight at lightweight against Japan's Daisuke Narimatsu, in front of a vocal home crowd here at Prince Hamzah Hall.

Odai Alhindawi then out-classed American Samoa's fourth seed Jolando Taala in the light heavyweight division, earning a unanimous decision from the judges.

All of the semi-finalists across the weight classes will qualify for Tokyo 2020, so the Jordanian pair are just one victory away.

Alkasbeh lost the first round as Narimatsu started strong in his bid to reach his home Olympics.

The Jordanian knocked the southpaw down in the second, however, and showed great energy in the third before taking the contest on a split decision.

"Nothing was going to stop me in there," he said.

"I felt I had all of Jordan behind me in the ring, the crowd was fantastic.

"He was a very strong opponent but I felt stronger as the fight went on."
